This paper shows how the great philosopher and mathematician Norbert Wiener founded Computer/ Information Ethics as a research discipline in the 1940s. Wiener envisioned the coming of an “automatic age” in which information technology would have profound social and ethical impacts upon the world. To analyze the ethical implications of such developments, Wiener presented some principles of justice and employed a powerful practical method of ethical analysis. The paper has resulted in a redefinition of the history of the discipline.
